Puma–livestock conflicts in the Americas: a review of the evidence

Abstract

AbstractLoss of livestock is one of the greatest sources of conflict between humans and large felids worldwide. The pumaPuma concoloris the most widespread apex predator in the Americas, and conflicts between this felid and humans are common throughout its geographical range. In response to predation on livestock, humans persecute and hunt pumas.We identified the main environmental and anthropogenic variables that define puma–livestock conflict areas in the Americas as 12 conflict predictor variables, and explored the techniques proposed to mitigate conflicts between the puma and livestock producers.We conducted a systematic search and subsequent review of the scientific literature and found 92 publications on puma–livestock conflicts. Through single‐variable analyses and generalised linear models (GLM), we identified which of the 12 conflict predictors were most predictive of the occurrence of predation.The single‐variable analyses showed that high livestock density (goat, sheep, and cattle), low latitudes, low habitat steepness, low co‐predator richness, high distance to habitat (shrub), and high distance to roads characterised areas with conflict. The binomial GLM indicated that areas with conflicts were primarily located in the temperate southern hemisphere and characterised by densities of livestock. The most frequently cited conflict mitigation techniques were ‘improving livestock management’, ‘predator control’, and the ‘use of fencing’.Although our knowledge about the puma and its relationships with human communities has improved, there are wide geographical gaps, and many facets of puma–livestock conflicts are still little understood. Scientists should work with local stakeholders to generate reliable information regarding the ecological and societal consequences of puma–livestock conflicts, and to develop conflict mitigation techniques that could facilitate the coexistence of pumas and humans.
